According to the comments on the Issue that you linked, this returned between 26.0.0 and 26.1.1.

I seem to be having this issue again with 26.1.1

I can confirm this is also happening to me on 26.1.1.

If that's the case, then this isn't specifically new to the OBS Studio 27 Release Candidates. Can you reproduce this on the 26.x releases?

I managed to reproduce on 26.x release. I had an older version before (maybe 25.x?) and, on then, the issue didnt happen.

So I've also had this issue in v27, but I've come up with a workaround solution utilizing the new Source Transition feature!

Make an Image Source of the last frame of your video and set the Show Transition (stinger) for it to your video file. This way when the transition ends, the video completely unloads and you have a seamless transition into the last frame as a still image. Done!

Noting that this continues to be a problem in OBS 27.2.1 on Mac. This old forum post does a really nice job of visualizing the issue: https://obsproject.com/forum/threads/media-source-rendering-the-last-frame-at-the-beginning.110180/

@mercantigo Are you still able to reproduce this on 29.0.2?

gravelfreeman commented 1 year ago

Unfortunately we changed our After Effects template and we're not using folders in OBS anymore so I can't tell.

SimonGZ commented 1 year ago

@tt2468 I'm not the original bug poster, but I can confirm this issue still exists on 29.0.2 on macOS 13.3.

When switching scenes to a scene with a media source that is set to restart playback when the source becomes active, the last frame of the media source will briefly flash on the screen before the video restarts.

I have tested this problem on 30.0.0 and unfortunately the problem remains (at least on my M1 Pro Macbook). I was hoping that #3206 would have fixed the issue but no, I still see the last frame of whatever video just played whenever I enter a slide with a media source set to "Restart playback when source becomes active"

Another way to experience this behavior is simply to toggle the visibility of the media element on and off. You'll see the last frame of the video pop in and then the video suddenly blink back to the beginning.

Before version 30, this bug was reproduced at 60 FPS, and from version 30+ this bug is reproduced at 30 FPS. That's why I always used 30 FPS. But now that doesn't help either. A very disgusting bug, it greatly affects the quality of the output video. I would even say that it becomes a shame for such quality of the video ((((

@mercantigo Are you still able to reproduce this on 29.0.2?

The bug is reproduced on all versions 29 and all versions 30. The most basic way to reproduce: 1) Make a transparent stinger 1 second long, set the transition to 500 ms 2) Make two scenes where in each a video file is played with a restart option 2) Constantly switching between two scenes

Is there any update to this issue? I've been monitoring this issue since February and am REALLY looking forward to this being fixed, but it doesn't seem to have went anywhere recently.
